   DAY 1 FIRE WEATHER OUTLOOK

   VALID 041200Z - 051200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR CENTRAL AND ERN ID / SWRN MT / WRN
   WY...
   
   ...SYNOPSIS...
   WARM AND DRY AIR WILL COVER MUCH OF THE COUNTRY TODAY...WITH STRONG
   UPPER RIDGE OVER THE CENTRAL STATES. CRITICAL FIRE WEATHER
   CONDITIONS WILL EXIST OVER PORTIONS OF THE NRN ROCKIES WITH DRY
   LIGHTNING DEVELOPING IN ASSOCIATION WITH AN UPPER TROUGH. TO THE
   SOUTH IT WILL REMAIN VERY DRY AND OCCASIONALLY WINDY OVER THE GREAT
   BASIN. FARTHER E...LOW PRESSURE WILL GRADUALLY DEEPEN OVER THE
   DAKOTAS WHICH WILL RESULT IN STRONG SLY WINDS AND LOWERING RH. IT
   WILL BE VERY WARM AND DRY OVER THE LOWER MS VALLEY AND SRN PLAINS
   DUE TO HIGH PRESSURE AND DRY NELY WINDS.
   
   ...CRITICAL FIRE WEATHER AREA 1 - CENTRAL AND ERN ID / SWRN MT / WRN
   WY...
   
   PRIMARY CONDITIONS: DRY LIGHTNING / LOW RH / GUSTY SWLY WINDS / MDT
   HAINES
   
   SCATTERED DRY THUNDERSTORMS ARE LIKELY THIS AFTERNOON FROM E-CENTRAL
   AND SERN ID INTO SWRN MT. IN ADDITION TO STORMS...IT WILL REMAIN
   VERY DRY WITH MODERATE WIND SPEEDS.
   
   WITH UPPER TROUGH SLOWLY AMPLIFYING TO THE NW...TEMPERATURES WILL
   COOL ALOFT COMPARED TO PREVIOUS DAY. AT THE SAME TIME...SURFACE
   TEMPERATURES WILL REMAIN WARM. THIS WILL STEEPEN LAPSE RATES AND
   CAUSE THUNDERSTORMS TO DEVELOP BY AFTERNOON. SUB-CLOUD RH LEVELS
   WILL BE LOW THUS LITTLE IF ANY RAIN IS EXPECTED WITH STORMS. GIVEN
   SWLY WINDS...DEVELOPMENT IS LIKELY OVER THE CENTRAL MTNS OF ID AS
   WELL AS THE UPPER SNAKE RIVER PLAIN INTO THE YELLOWSTONE AREA. IT IS
   DIFFICULT TO TELL WHERE THE WRN EDGE OF THE LIGHTNING WILL BE AS
   SWLY WINDS WILL BE DRYING THE AREA OUT WITH TIME...THUS...SWRN
   PORTIONS OF THE CRITICAL AREA MAY NOT SEE MORE THAN ISOLATED
   STRIKES. STRONG WINDS ALOFT WILL CARRY STORMS NEWD WITH TIME...WHERE
   THEY WILL TRANSITION TO WET OVER W-CENTRAL MT.
   
   IN ADDITION TO STORMS...RH WILL REMAIN LOW AND IN THE TEENS WITH
   SUSTAINED SWLY WINDS OF 15-20 MPH AND GUSTY. LOCALLY STRONG WINDS
   GUSTS FROM THUNDERSTORMS WILL FURTHER ENHANCE THE RISK OF ERRATIC
   WILDFIRE BEHAVIOR WITH MDT HAINES.
   
   ...ERN TX / SRN AR / NRN LA...
   CONDITIONS WILL BE DRIER THAN PREVIOUS DAY AS NELY WINDS DUE TO HIGH
   PRESSURE CONTINUE. SUSTAINED WINDS OF 10 MPH WILL OCCUR WITH GUSTS
   OVER 15 MPH. AFTERNOON TEMPERATURES WILL RISE INTO THE 90S AND
   SINKING AIR ALOFT WILL CAUSE RH LEVELS TO DROP CRITICALLY LOW INTO
   THE 20-25 PERCENT RANGE. HIGH KBDI VALUES ABOVE 700 SUGGEST HIGHER
   THAN NORMAL THREAT OF FIRES...ESPECIALLY IN AREAS SUCH AS SW AR
   WHICH HAVE RECEIVED LITTLE RAIN IN THE PAST WEEK.
   
   ...SRN SIERRA INTO SRN NV AND WRN UT...
   MARGINAL FIRE WEATHER CONCERNS ARE ANTICIPATED FOR TODAY...DUE TO
   WINDY AND DRY CONDITIONS. WIND SPEED WILL BE THE PRIMARY MITIGATING
   FACTOR...WITH SUSTAINED SLY SPEEDS ONLY NEAR 15 MPH. GUSTS WILL BE
   HIGHER THOUGH DURING THE AFTERNOON WITH A FEW APPROACHING 25-30 MPH.
   IT WILL CONTINUE TO BE VERY DRY WITH MIN RH VALUES NEAR 10 PERCENT.
   STRONG HEATING IN COMBINATION WITH COOL AIR ALOFT WILL CAUSE STEEP
   LAPSE RATES WITH HIGH HAINES.
   
   ...CENTRAL AND WRN SD / SRN ND...
   STRONG SLY WINDS WILL DEVELOP TODAY DUE TO SURFACE PRESSURE
   GRADIENT. SUSTAINED SPEEDS NEAR 20 MPH WILL OCCUR WITH HIGHER
   GUSTS...WHILE RH LEVELS DROP TO 20-30 PERCENT. FUELS ARE DRY BUT
   THUNDERSTORMS ARE EXPECTED TO DEVELOP BY LATE AFTERNOON NEAR A LOW
   PRESSURE TROUGH FROM NEAR BISMARK SWD INTO CENTRAL AND WRN SD.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0225 AM CDT SUN SEP 04 2005
   
   VALID 051200Z - 061200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   MAIN ENERGY ASSOCIATED WITH UPPER TROUGH WILL MOVE EWD INTO THE
   EXTREME NRN PLAINS AND SRN CANADA ON MONDAY...BRINGING A COLD FRONT
   E INTO THE ERN DAKOTAS. THIS FRONT WILL STRETCH WWD ACROSS SRN MT
   AND CENTRAL ID...SOUTH OF WHICH IT WILL REMAIN DRY WITH GUSTY
   AFTERNOON WINDS. TO THE EAST...IT WILL BE VERY WINDY OVER THE
   CENTRAL AND NRN PLAINS BUT RH VALUES WILL NOT BE PARTICULARLY LOW.
   HIGH PRESSURE WILL REMAIN AT THE SURFACE ACROSS THE ERN HALF OF THE
   NATION...BUT RH LEVELS WILL NOT BE AS LOW AS SUNDAY OVER SRN MS
   VALLEY REGION AND WINDS WILL BE WEAKER.
   
   ...GREAT BASIN INTO SRN ID...
   WINDS WILL NOT BE STRONG MONDAY BUT IT WILL REMAIN DRY. MIN RH
   VALUES WILL RANGE FROM 10-15 PERCENT OVER NV TO 15-20 PERCENT OVER
   SRN ID. DEPENDING UPON HOW MUCH LIGHTNING THERE IS ON
   SUNDAY...THREAT FOR ADDITIONAL FIRES WILL EXIST WITH TEMPERATURES IN
   THE 80S AND MDT HAINES FORECAST. WITH A WEAK FRONTAL BOUNDARY IN
   PLACE OVER SRN MT...ISOLATED THUNDERSTORMS ARE EXPECTED ACROSS SRN
   MT INTO E-CENTRAL ID. COOL TEMPERATURES ALOFT AND UPSLOPE FLOW MAY
   ALLOW FOR ISOLATED STRIKES INTO THE WASATCH AS WELL.
